As many of you know there will not be any mmr reset: As some of you have noticed, MMR did not reset today with the start of Season 12. This was indeed a last minute decision and we apologize for any confusion this has caused. (http://us.battle.net...7021?page=6#106)

I for once do not understand why they do this mistake again. What would the upside be really?

They should end up resetting mmr 1-2 weeks in like in s9, along with team resets if not welcome to another season where people grab rating even sooner and camp even earlier. Also Add rating decay for idiots who sit ffs....
